Consider a system on which there are external forces acting. If the vector sum of all these external forces is zero, then the centre of mass _____ Correct Answer may move

Since the vector addition of all external forces is zero, we know that the acceleration vector is zero for the resultant force vector as mass cannot be zero. Zero acceleration can imply zero or non-zero constant velocity. Thus, the centre of mass may move.
